STEM Keynote

keynote_at_stem_divide_cvjAs I mentioned, a couple of Saturdays ago I gave the keynote address at a one-day conference designed to introduce STEM Careers to underrepresented students from various neighboring schools. The event* was co-sponsored by the Level Playing Field Institute, but sadly the details of it seem to have vanished from their site now that the event has passed, which is unfortunate. It was good to see a room full of enthusiastic students wanting to learn more about such careers (STEM = Science, Technology, Engineering and Mathematics) and I tried to give some thoughts about some of the reasons that there’s such poor representation by people of color (the group I was asked to focus on, although I mentioned that many of my remarks also extended to women to some extent) in such fields, and what can be done about it. Much of my focus, as you can guess from the issues I bring up here from time to time, was on battling the Culture: The perception people have of who “belongs” and who does not, and how that perception makes people act, consciously or otherwise, the images we as a society present and perpetuate in our media and in our conversations and conventions throughout everyday life, and so on. I used my own experience as an example at various points, which may or may not have been helpful – I don’t know.

My experience, in part and in brief, is this: I went a long way into being excited [...] Click to continue reading this post

Baby Mothra!!!

So I discovered a terrifying (but also kind of fascinating and beautiful at the same time) new element to the garden this morning. We’re having a heat wave here, and so this morning before leaving for work I thought I’d give the tomato plants a spot of moisture. I passed one of the tomato clusters and noticed that one of the (still green) tomatoes had a large bite taken out of it. I assumed it was an experimental bite from a squirrel (my nemesis – or one of them), and muttered dark things under my breath and then prepared to move away the strange coiled leaf that seemed to be on top of it. Then I noticed.

It wasn’t a leaf.

It was a HUGE caterpillar! Enormous! Giant and green with spots and even a red horn at one end! There’s a moment when you’re unexpectedly close to a creature like that where your skin crawls for a bit. Well, mine did for a while [...] Click to continue reading this post

Screen Junkies Chat: Guardians of the Galaxy

Screen Shot 2014-09-11 at 3.13.03 PMYou may recall that back in June I had a chat with Hal Rudnick over at Screen Junkies about science and time travel in various movies (including the recent “X-Men: Days of Future Past”). It was a lot of fun, and people seemed to like it a lot. Well, some good news: On Tuesday we recorded (along with my Biophysicist colleague Moh El-Naggar) another chat for Screen Junkies, this time talking a bit about the fun movie “Guardians of the Galaxy”! Again, a lot of fun was had… I wish you could hear all of the science (and more) that we went into, but rest assured that they* did a great job of capturing some of it in this eight-minute episode. Have a look. (Embed below the more-click):

But How…?

I get questions from time to time about where the drawings on the site come from, or how they are done. notebook_and_tools The drawing I had in one of last week’s posts is a good example of one that can raise questions, partly because you don’t get a sense of scale after I’ve done a scan and cropped off the notebook edges and so forth. Also, people are not expecting much in the way of colour from drawing on location. Anyway, the answer is, yes I drew it, and yes it was drawn on location. I was just sitting on a balcony, chose which part of the view I wanted to represent on the page, and went for it. I wanted to spread across two pages of my notebook and make something of a tall sketch. See above right (click for larger view.) A quick light pencil rough helped me place things, and then a black [...] Click to continue reading this post

Coral Forest

crochet_forest_7Given that you read here at this blog, you may well like to keep your boundaries between art and science nicely blurred, in which case you might like to learn more about the coral reef forests made of crochet spearheaded by Margaret and Christine Wertheim. The pieces mix crochet (a hand-craft I know and love well from my childhood – I got to explore my love for symmetry, patterns, and problem-solving by making doilies) with mathematics – hyperbolic geometry in particular – as well as biology (mimicking and celebrating the forms of corals – and drawing attention to their destruction in the wild). You can read much more about the projects here. I’ve mentioned the work here before on the blog, but the other day I went along to see a new set [...] Click to continue reading this post

Making and Baking….

Back in LA, I had an amusing day the other day going from this* in the TV studio…
photo_laser_mirage_shoot_small involving a laser and liquid nitrogen (so, around -320 F, if you must use those units), to this in the kitchen:

Aspen Art Museum Opening

aspen_Art_museum_new_building_7_aug_2014_04

I just got back from the Aspen Art Museum‘s new building. They’ve been having a members-only series of nights before the big opening to the public in a few days, and an invitation was sent along to Aspen Center for Physics people to come along, and so (of course) I did. It was a nice thing to do at the end of a day of working on revising drafts of two papers, before settling down to a nice dinner of squash, green beans, tomatoes, and lemon-pepper pasta that I made, all from the Saturday Farmers’ Market. But I digress.

Let me say right at the outset that the building is fantastic. There will no doubt be arguments back and forth about the suitability of the building for the town, and so forth (and there have been), but as a space for both art and community (and to my mind, those should go together in a city’s main art space) it is simply [...] Click to continue reading this post

In Motion…

subway_sketch_5th_august_2014_smallBack in Aspen. I went back to LA for a long weekend, and my travel back to Aspen today gave me a lot of good thinking time. Also, I got a few very quick drawings done, such as the one on the right of a cooperative fellow (looking at his phone) on the subway on my way to Union station to take the LAX Flyaway bus.

I’ve been thinking about two projects, one physics and the other about physics, going back and forth between the one and the other, trying to not let them interfere with each other. The “about physics” one is of course the graphic physics book project. In itself it is in two parts. I’m adding more pages from time to time – drawing, inking, and painting/colouring when I can – and I’m also having the odd conversation with potential publishers from time to time, and sending off proposal packages to appropriate places that accept them… trying to explain the nature of the project to those who are willing to listen to something new and exciting. As I’ve said before, “new and exciting” are not words that most publishers want to [...] Click to continue reading this post

Fireworks!

It is the 4th of July, and I hope you who are celebrating it have a good time today!

Morning Sex

gardening_3rd_july_2014_2Yep. This is an exciting new discovery for me. No, it is not what you think! I’m talking about gardening matters. It seems that a lot of my cucumber and squash plants are not producing a great deal this year, (with several small squashes not developing much before falling off) and I could not figure out why. On the other hand, I’ve done a better job of building sun shields for them, to stop them being fried by the intense heat over the course of a hot day. I now think that maybe these things are connected. First of all, I’m not seeing a lot of bees of any sort in the garden, and so I wonder if it is simply that there’s not a lot of pollination going on. Couple this with the fact that the sunscreens (some quite low) are probably hiding them from some bees that might be passing by, I’ve begun to wonder if it is time to help things along a bit.

Magazine Practice

magazine_sketch_16_06_2014_smallAs a way of degaussing from the heat of physics research involved in producing the recent paper, I spent a bit of time getting my hand back into some proper drawing shape… I looked into some magazines and catalogues for interesting faces and found a couple.

magazine_sketch_18_06_2014_smallThe woman was done more or less directly in ink, which is a good challenge for the eye – you must be sure about a line before you put it down, since you’ve not got a second chance. A day or two later I sat in a cafe after a visit to a garden centre to pick up some supplies, to draw another interesting face I found (in a gardening catalogue). This was done more carefully, starting by doing a quick pencil sketch first for accurate layout, and then doing ink afterwards. Since people are sometimes curious about process, I include below a sequence of stages on this one as well. Enjoy.

Swoosh!

swooshWell, I sort of disappeared there for about a week. I got lost in some really interesting physics and had a lot of fun doing it.

I kept walking away, and it kept bringing me back. There’s that fun groove one can get into that other theorists will recognise: You hit an interesting vein where you can calculate interesting results in a particular model, and you just can’t help yourself computing more and more [...] Click to continue reading this post

Stockpiling Notebooks

notebook_supplyAs you know from my writings and sketches, I like to carry a notebook. People often ask me what types I use, or assume that I use the (increasingly fashionable) Moleskine books. I like Moleskine books (the little 3inx5in ones for example), and have used them a lot in the past, but actually I prefer the books by HandBook Journal Co., (made by Global Art Materials). The surface of the paper is more flexible, in my opinion. It has a little more tooth than standard Moleskine, which makes mark-making with pencil much surer, and it also takes wetting better,airline_sketches_9th_july_2013 so you can work with a little wetness as well, such as lots of ink, or watercolour (paint- or pencil-based). That allows for crisp drawings like the one on the right (click for larger view – more about these sketches here), right alongside physics research musings and computations in pen and ink line on the pages shown below on the left (those notes pertain to the paper I discussed here.)

I tend to carry one of the 8.25inx5.5in landscape ones (although I love the 5.5in square ones too). (See more chat about them here.) They allow a good [...] Click to continue reading this post

Honest Time Travel?

On Tuesday I hung out with some of the Screen Junkies folks who you may know from the hilarious “Honest Movie Trailers” web series (seriously, if you’ve not seen any of them, please go right now and have a look). We had a fun chat about time travel in movies, and presenter Hal Rudnick and I bonded over various movies old and new. The final version of the show is up on YouTube (embed below), and I’m bummed that I did not get to meet the other guest, Christina Heinlein (JPL), who seems fun – and is a descendant of, yes, that Heinlein. I love the idea that she works at JPL, helping make possible the space exploration that Robert Heinlein helped inspire us all about in his writing. Anyway, enjoy the short piece (I wish you could see a bunch of the other material too… we really had a great chat about the ins and outs of time travel, but a lot of it inevitably ended up not making the cut…)

I could not resist talking about my view of this (perhaps growing) trend of using time travel as a means of resetting movie franchises (see Star Trek, X-Men…). It’s a great way of repairing writing and other filmmaking wrong turns. Feel free to imagine your own version of this – Star Wars anyone? Another pass at [...] Click to continue reading this post

How I Sometimes Feel

tar_pits_entrapment_eventIn fact, the last several days have felt like this, with regards big decisions about various administrative roles I’ve been asked to consider taking on. It never seems to end, and I am terrible at saying no to as many things as I should. And I have a bad habit of doing things to the best of my ability and hence I get a reputation as the guy to ask to do a task since I did a good job last time, and so it gets me sucked in deeper into the administrative quagmire, and so on and so forth.

Rather like the “entrapment events” that happened in the La Brea Tar Pits so long ago (have a read of what I wrote about those on a field trip to the Page Museum a while back). I was wandering around the LACMA and Tar Pits grounds yesterday evening after a shoot for a show (a fun thing coming that I’ll let you know about shortly) and made a phone call to say, after ten days of [...] Click to continue reading this post

Bent Cog

bent_cog_bromptonHere’s what almost ruined my morning on Monday. I decided to cycle the Brompton all the way into work, and went a different way as a change of scenery. At some point, my bike chain started making quite the racket, with a jarring action as I pedalled, but there was nothing visible wrong with the chain, and the gears seemed to be working just fine in terms of shifting – but the problem persists in all gears: The chain keeps trying to jump off the rear wheel every few inches, and then pops back on again. I could not see the problem at all, and I had to get into work for a meeting. My working theory was that I’d stretched the chain somehow so that it no longer fits the bike, but none of the tools I had were going to be able to help with that.

Happily, that different way I’d chosen meant that I could struggle on for a bit longer (enough to get me out of traffic, and do a bit of coasting when I could) and then walk the Brompton over from the end of Virgil to the subway stop at Wilshire and Vermont and complete my journey using the Red and Expo lines.

When I got it home, I put the bike on the high stand, and did a bit of investigation with the better visibility, and there it was. Bizarrely, the larger of [...] Click to continue reading this post

Sketchy Freedom

downtown_towers_26_05_2014Memorial Day – 26th May 2014. I arrive at downtown Los Angeles to enjoy a few moments of the pure joy of looking. Of seeing something in front of me well enough to make a rough representation of it on a piece of paper in front of me, for the pure hell of it. This is the essence of sketching. It is about seeing. I’m looking for the… something.

My hunt is over. I see the scene I want, just off the Water Court, a few minutes from the top of the (closed) Angel’s Flight rail. The sun is streaming through the portal framed by the two closest buildings. The further ones make sharp geometry against the 4:00pm sky. I’m also curious to try some new coloured pens, and I like that each building suggests a different colour. I’ve got about 15 minutes before I have to leave to pick someone up.

I sit. I start. Immediately I see the guard see me from across the way, and within a minute or two he is by my side, standing in front of me. He has the “You’re not allowed to do X” look on his face, but he’s trying to start out well. I’ve had this before, right in this public space, when a guard decided that I should not take photos of the buildings. Despite all the other tourists who do so. He begins:

You know, usually we… Are you an architecture student?

Excuse me?

Are you an architecture student?

Well, what are you asking me, really?

News From the Front XII: The Nuts and Bolts of Enthalpy in Quantum Gravity

So it happened again. I got musing to myself about something and decided to do a quick computation to check it out, and it took me down an interesting rabbit hole, which resulted in me writing a nice little paper at the end of last week that appeared today on the arxiv. I think the physics is really really nice. Let me tell you a bit about it. It is in the same area of ideas that I mentioned last time, concerning that paper I wrote last month. So let me pick up the story there, since I did not really touch on the core of the story. [Note: for non-experts, the following will get somewhat technical and full of terms and ideas that I will not explain. Sorry.]

One of the things that might have struck you (if you’re an expert in the area) from my proposal to make heat engines out of black holes that do real mechanical work like the engines you read about in physics textbooks is that there ought to be no actual mechanical work since there’s no pistons – no pistons changing volumes and so forth. That is (or rather, was) a missing ingredient in the standard thermodynamics of black holes in quantum gravity. Well, that all changed a short few years ago with the work of a number of authors, particularly with the clear suggestion of David Kastor, Sourya Ray, and Jennie Traschen, and work by Brian Dolan, with a fair bit of followup investigations by various other authors including some I’ll mention below. (Update: Two reviews, with different foci, can be found in here and here.) The general idea is that if you allow the cosmological constant \Lambda to be a thermodynamical variable as well (and there is a long history of authors considering this in various contexts), where it naturally acts like a pressure p = -\Lambda/8\pi G, (G is Newton’s constant, and I’m setting various other constants to unity in the usual way) then you naturally include a conjugate to that variable that should be the pressure.

For a simple static black hole like Schwarzschild, the volume turns out to the the naive volume you get by taking the radius of the black hole and forming [...] Click to continue reading this post

Making Marks

Been a while since I got to do some sketching. It is good practice to try to do something every day, but that fell by the wayside a little as far as proper sketches went. It has been busy the last week and a bit, and my subway time has been during very busy times when there’s not enough space to get out pen and paper and sketch a person without becoming a spectacle… and during the moments where I might have caught something, I’ve actually been calculating – working out questions for the final exam in the General Relativity class, and (more recently) doing some computations for a paper I’ll tell you about shortly.

Anyway, when time is short, I sometimes like doing quick sketches with a thicker pen. Stops me from digging into the details too much. In fact, I’m really liking that as a sketch mode these days… You make your lines boldly and you’re stuck with your choices, and so it gets you thinking about what’s globally important carefully before jumping in.

A New Shower!

Camelopardalids_2014-Radiant_HD1….Let’s hope it is not equipped with a low-flow shower head though. If you get a chance this evening, find a wide area of sky away from as many lights as you can (it does not have to be perfectly dark, but the darker the better). There is a new meteor shower, the Camelopardalids…. It is new because the comet debris responsible (we’re flying through debris left over from its tail) has not intersected with our orbit before, but things have been changing a bit (apparently due to Jupiter’s gravitational pull) and as a result we’ll go right through it for the first time (as far as records show). It is expected that there’s a good chance that it will be a high event shower, and it has also been said – I forgot where I read this – that the [...] Click to continue reading this post

Shade Emergency!

Well, making it was a bit like a Lego project, and so… fun! Basically, it is ridiculously hot here. The last couple of days have been over 100 degrees Fahrenheit and there are more days of this sort to come. This is not pleasant, in my view. I tend to operate very poorly at such temperatures, and the sun is oppressively hot, feeling like it is hammering on your head, neck, any exposed areas. (We had a wave of this sort a few weeks ago too, which resulted in a new investments in a new shape of hat.)

My main concern however is the various plants in the garden. The planting of Summer crops this year was quite late (largely because the Winter crops were slow to develop due to lack of Winter rain) and so they are still at the delicate stage where a day or two of strong hot sunlight can destroy them completely. No amount of watering can save them from this sun. So I decided to make some shades to reduce the amount of sun on various plants in the garden and on the patio. The idea was to make a nice geometrical shape that allows the plants to be nicely displayed while at the same time protecting them from that mid-morning to mid-afternoon hammering heat that I’ve seen burning the leaves on several plants. I put together a prototype design, and you can see the steps in the photos: [...] Click to continue reading this post

Advice at Graduation

It is Commencement on Friday, here at USC. Thousands of students will be dressing up in gowns and taking part of the ceremonies marking the ending of their time here at USC and the beginning of the rest of their lives. It’s an exciting time.

Merrill Balassone and a team from USC Media Relations came by my office a few weeks ago to take 15-20 minutes of time to do a prototype of a project on this very subject of commencement. The result was fun, and apparently they used it to build onto in order to make the final short video you can see below. advice_film_stillThey did a great job! It is a group of USC professors and staff** giving brief thoughts to graduating students upon their graduation. You’ll maybe guess what I say in my segment. It is a theme I mention here a lot, as part of my personal war on people being shut out of (or shutting themselves out of) participation in aspects of our society.

Metro Goes for All the Science Tropes

science_metro_poster I think the people at LA Metro were trying to go for all of the visual science tropes in one cliché-filled glance! I’m a big fan of LA Metro, as you know from several posts about it here, so don’t misunderstand my poking fun at their ad I spotted on a bus stop bench. I think it is to do with helpful apps for your phone – presumably they help you use the system more easily, because of…science? More generally, I’d love to believe that people will take the train more because scientists are involved in designing the logistics, but there’s so much evidence against this on both counts, like having the Blue line and the Expo line – that share the same main platform – both boast BLUE as their colours. But put that all aside for now, and let’s simply count off all the sure-fire imagery that will [...] Click to continue reading this post

Old School Writer

posting_stuff…Yeah. Somehow sending proposals and samples of manuscripts around by email does not really feel super-exciting to me. But it is the way things are done now, it seems. But this afternoon, I found myself doing something very old-school, which I rather enjoyed, perhaps because it connected me with writers through the ages: Printing up some special packages (proposal, samples, etc, of the book project), putting them into envelopes and schlepping them down to the post office, getting in line, and [...] Click to continue reading this post
